OpenStudy (anonymous):

what did u get

OpenStudy (strawberry17):

I will show you how I solved it

OpenStudy (jim766):

mult both sides by 9, then add 3

OpenStudy (anonymous):

OpenStudy (strawberry17):

Oh, okay, you just wrote it wrong :)

OpenStudy (anonymous):

sorry i didnt know how to write it

OpenStudy (strawberry17):

so then you will multiply 9 and 10 together and get rid of the divided sign and get: -3 + m = 90 Then you just subtract -3 from 90: 90 - (-3) = m
